Unfortunately, regarding the BIOS, I couldn't get more than that and now it's too late because I've already erased the chip to write on it...

Hello, the BIOS of an HP 250 G6 Motherboard: DKL50/CSL52 LA-E821P was corrupted following an update. When performing a clear CMOS, the message 'CMOS checksum invalid...' is displayed at startup, and then, when the computer restarts after pressing "F1", a black screen appears with a consumption of about 0.220 A.
I followed the procedures: I backed up the computer's BIOS, then downloaded the update file for the latest BIOS available on the HP website and extracted the BIOS files. There are 5 different ones: 084D4.bin; 0832D.bin; 0832E.bin; 08328.bin; 08445.bin.

Packard Bell N15W4: ALT and ALTGR keys not working
After installing Windows 10 from an ISO, a task I regularly perform 5 days a week, I encountered an issue with a Packard Bell N15W4: the ALT and ALT GR keys (on a French AZERTY keyboard) are no longer working. Of course, basic operations such as reinstalling the keyboard through the device manager have been unsuccessful. Currently, I no longer have physical access to the computer, and during remote access, my keyboard correctly sends the ALT and ALT GR signals to the concerned computer. Do you have any suggestions? Is there a specific firmware for the keyboard? Despite my searches on the internet,...

Hello, you mention that the problem has been solved. How did you resolve it? Was it by changing the coils on the screen's board? I am interested because I am facing the exact same issue with an ASUS X553M. Sharing your solution could greatly help the community. Thank you for your response...

Crossover for NCT7717U Thermal sensor
Hello, I am looking for an equivalent to the NCT7717U, it's a thermal sensor on an ASUS X553MA motherboard, can you help me?

Thank you for this response. Point to consider:
the screen backlight works on mains power. It also works when an external monitor is connected to the HDMI port in battery mode. The battery is new, and the phenomenon occurs with both the old and new batteries. The computer and display work normally on battery, it's only the backlight in battery mode that does not work. In this case, can we suspect a problem with the inverter or a component on the screen's board?...

Asus X453MA Rev 2.0 Backlight and fan
Hello,
I brought an Asus X453MA into the workshop, its owner tells me that it doesn't work on battery despite having replaced it with a new one and that it's making noise. I diagnose and find, firstly, that the fan is constantly running at full speed. Secondly, that the computer works on battery but there's no backlight when the charger is not connected. I look at the screen connector because I see that the adhesive is not holding. I observe that there probably was a short circuit. I isolated everything with hot glue and reassembled it, I don't think it needs to be replaced. The BIOS is...1 Photo

Sleep mode on HP PAVILION 11-n000nf laptop
Hello everyone,
I have an issue with my HP PAVILION 11-n000nf laptop. When it goes into deep sleep mode, it doesn't restart properly. The fan comes back on, power consumption is around 250 mA, but the screen remains black, and the Caps Lock key blinks. To resolve this problem, I have to disconnect the battery to shut it down. However, afterward, it doesn't restart normally. When I press the power button, it goes back to the same state as before. To get it back to working condition, I need to disconnect the CMOS battery and reset the BIOS. Of course, I know that if I prevent the...
